Michael Jackson - Katherine Jackson Still Struggles To 'Cope'

MICHAEL JACKSON's mum KATHERINE is still heartbroken over the superstar's death, insisting she undergoes a daily struggle to "cope" with her grief.

The Thriller icon passed away in June last year (09) after suffering a cardiac arrest, and the Jackson family matriarch was subsequently named guardian of the singer's children, Prince, 13, Paris, 12, and eight-year-old Blanket.

In a new interview, the 80 year old is visibly upset as she admits she has been an emotional wreck looking after her son's estate and kids in the year since his passing.

She says, "I haven't been doing so well but with Prince, family, loved ones and with prayer, I cope. Not a day goes by that I don't think about my son."

The footage is set to be included in an upcoming documentary about the star's life, reports TMZ.com.
